    Hi all,
    I have a problem about the steering PU2 pump alarm. The alarm is about PU2 OVERL/PHASE. I checked the input , output phase and the fuse in the starter . it's normal. Now I reinstalled all fuse . The alarm reset OK. So what is the problem is? And what is the next step if the alarm appear again?

    Did you replace the fuse with new? If not and it happens after awhile I'd suspect the fuse. If it happens with a new fuse I'd suspect a short and look for an area where the lines rub or are pinched,
